Currently, there is no easy way to achieve your needs in PowerApps. I agree with @RezaDorrani 's thought almost, I think the PowerApps Reviewer Tool could achieve your needs.

On your side, you could consider save your PowerApps app into a local file (.msapp), then run the PowerApps Reviewer Tool to open the local msapp file. After that, the properties of your app would show up as below:

Then you could do a search based on your flow's name, then you could find where the flow connection is used.

Re: How to see where flow is used in my app (screen/button)?

I don't think there is an easy way to do this. But, If you go to the Action menu and select Flows you can see any Flows that are associated with the PowerApp. If you remove them your PowerApps error checker will tell you what button the Flow run command is on. Then you can re-associate the Flow and should be OK.
